    摘要:

    以试制的纳米铜添加剂为试验单剂,选择车辆齿轮油500SN为基础油,在长磨实验条件下,进行纳米铜粉的抗磨和减摩性能试探性研究,探讨纳米金属粉体对车辆齿轮油500SN性能的影响.在1 200 r/min、2 h、98 N的条件下,加入质量分数为0.05%的实验制备纳米铜粉可明显提高基础油的抗磨减摩性能,磨斑直径降低了18.1%,摩擦系数降低了13.6%;在1 200 r/min、2 h、392 N的条件下,加入质量分数为0.05%~0.7%的纳米铜粉可以提高基础油的抗磨性能.随着质量分数的逐渐增大,纳米铜粉的抗磨减摩性能逐渐变差,以质量分数为0.05%的纳米铜粉效果最佳.

    Abstract:

    An exploratory study of anti-wear and friction reduction properties was carried out on the long grinding conditions to investigate the effect of copper nanoparticles as lubricant additive on the vehicle gear oil 500SN.Lubricant performances were tested at different burden and mass percentage of metal nanoparticles under the condition of 1200r/min and 2h.When the burden is 98N and the mass percentage of copper nanoparticles is 0.05%,the property of anti-wear and antifriction of the lubricant oil can be significantly improved,with the wear scar diameter being reduced by 18.1% and the friction coefficient being reduced by 13.6%.When the burden is changed to 392N,the anti-wear performance of the lubricant oil can also be improved with the mass percentage of copper nanoparticles varied from 0.05% to 0.7%,while the capacity of anti-wear and antifriction decreases for the copper nanoparticles as the mass percentage of metal nanoparticles increases.Thus the best percentage of copper nanoparticles as lubricant additive is 0.05% in mass percentage.
